摘　　要：按常规方法设计小模数少齿数类齿轮的齿形 ,在加工时容易出现根切现象 ,致使齿轮抗弯强度降低 ,啮合条件恶化。采用新型拟合曲线设计精密小模数少齿数齿轮的齿形 ,并使用电火花线切割方式进行加工 ,可有效解决上述问题。Due to the tooth undercut, the gears with small module and small tooth number machined with conventional method usually have lower bending strength and unfavourable mesh character. This can be avioded by calculating the tooth profile with curve fitting and then cutting this kind of gear on WEDM machine.
